Draining the Seawater System
!
CAUTION
Water can enter the bilge when the drain system is open, damaging the engine or causing the boat to sink. Remove the boat
from the water or close the seacock, disconnect and plug the seawater inlet hose, and ensure the bilge pump is operational
before draining. Do not operate the engine with the drain system open.
IMPORTANT: Only drain the seawater section of the closed‑cooling system.
IMPORTANT: The boat must be as level as possible to ensure complete draining of the cooling system.
Your power package is equipped with a drain system. Refer to
Drain System Identification
to determine which instructions apply
to your power package.
IMPORTANT: The engine must not be operating at any point during the draining procedure.
IMPORTANT: Mercury MerCruiser requires that propylene glycol antifreeze, mixed to the manufacturer's instructions, be used in
the seawater section of the cooling system for freezing temperatures or extended storage. Make sure that the propylene glycol
antifreeze contains a rust inhibitor and is recommended for use in marine engines. Be certain to follow the propylene glycol
manufacturer's recommendations.
